A silvery metal, that generates huge amounts of raw energy. This is the most solid source of energy that exists in the universe. A small piece of Eternium can provide enough energy to power an entire planet for centuries. The Eternium is also incredibly rare, occasionally finding small pieces or nuggets among rocks, never as deposits or reefs. It is so rare that not even the Royal Family Of Eternos can afford to keep a stock of emergency Eternium. Apparently, Eternium can also be consumed in small fragments by robots or semi-mechanical beings to get a huge jolt of raw power for short periods of time. It also has teleportation properties.
